Yes, you can spend a bundle to have a sleepover party at the Bronx Zoo, and we admit that sounds really cool, but if you don't want to spend the rent money on a child's birthday party you can party with the whales and the sharks at The New York Aquarium. Prices start around $350 to party in the deep. The New York Hall of Science hosts a slew of super parties. No matter what your budding Einstein is interested in, there's sure to be a party they'll love here. Parties start at $500. Science Teacher Sarah does really fun, hands-on science parties for kids. You can have the birthday party in her classroom, but if you have the space and want to save money, you can do it at your place starting at just $245. For a truly only-in-New York birthday party, check out the parties at The Museum of the Moving Image. Kids can put their own voices into classics like The Wizard of Oz, check out special effects dolls from Star Wars, make their own animation and more. This unique experience starts at only $450. I don't know what kid wouldn't think the birthday party at robot village is super cool. Kids get to make their own robots, hello! These parties may be a little pricier, with the big package starting at $700, but they said they can strip it down for a less expensive party.
